Nothing. If successful, it creates a prepared statement inside the server. It might possibly make sense for a libpq routine that exposes Parse to actually do Parse followed by Describe Statement; that would allow it to give back (a) an indication of the number and types of parameters needed by the statement, and (b) an indication of the column set to be returned, if it's a SELECT. However, the protocol doesn't tell anything about the type of a non-SELECT statement. In any case, this would require more invention and coding than I care to do at this point in the release cycle (since there's no support in the guts of libpq for accepting ParameterDescription messages from the backend). If that's what we think we want, we'd better put it on the wish-list for 7.5. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
